Definitions

  • the invention relates to a method for cleaning in the production of olive oil in each applied production processes with different Water content or organic matter content resulting waste water.
  • the biological treatment of wastewater is limited set, provided it, such as that in olive oil production resulting waste water, antibacterial Contains ingredients.
  • the invention is therefore based on the object of a method for cleaning olive oil production waste water to indicate that an essentially economic one complete removal of organic components guaranteed so that a cleaned of dyes and odors free wastewater for irrigation purposes or available for reuse in production stands or can be directed into water.
  • the object is achieved with a method in the biological treatment of waste water with microorganisms, a first process step for mechanical Separation of the solids present in the wastewater and oil components and then a physical one second process step for selective adsorption the phenolic components of wastewater in one Upstream ion exchange process on an adsorber resin is.
  • the basic idea of the invention to achieve an environmentally friendly effective cleaning is removal of the phenolic constituents of the waste water their adsorption on a special adsorber resin in one Ion exchange process and only afterwards performed biodegradation of the remaining organic Substances with the help of microorganisms, in which the previously removed phenolic components of a biological No longer stand in the way of treatment.
  • the adsorption step is the removal of the solid components and the oil in the wastewater is preceded by to ensure the functionality of the adsorber by for example clogging of the adsorbent layer is prevented with solids.
  • Characteristic is biological purification first an anaerobic process and then in an aerobic Process carried out, in addition to in the anaerobic process the breakdown of low molecular weight organic substances at the same time an activation of the high molecular organic Substances for their biodegradation in the subsequent aerobic step takes place.
  • An embodiment of the invention is based on the Drawing, in the single figure a device for Implementation of the process for the purification of waste water from olive oil production using the example of the three-phase Manufacturing process according to Alpechins the individual process steps schematically is illustrated, explained in more detail.
  • a separator here one Hydrocyclone 2
  • the separation stage a Filter press (not shown) used.
  • Hydrocyclones 1 can also use other separation devices, e.g. a filter centrifuge with a vacuum filter connected to it, be used.
  • this first step is the proportion of solid components in the wastewater reduced to less than 0.1%.
  • the wastewater will have a preventive effect first in an anaerobic and then in one aerobic fermentation stage biologically cleaned, namely without the growth of the microorganisms by the phenolic Components can be hindered.
  • anaerobic bioreactor 4 are in the absence of oxygen first the low molecular weight organic substances, such as organic acids, fats, sugars and the like Metabolic processes degraded. This creates biogas that can be used to generate energy.
  • the wastewater then enters an aerobic bioreactor 6, in which the high molecular weight organic substances biodegradable with air supply.
  • the one there resulting exhaust air is in a biofilter 7 and Activated carbon filter 8 cleaned and deodorized and then led outside.
  • a decolourization step follows, in which the remaining organic matter essentially be removed and the hitherto still brownish Liquid is decolorized.
  • the clarification level is formed by a nanofiltration module 9 through which the macromolecular organic dyes in one Fine filters are retained so that clear, essentially water free of organic substances in one subsequent receiving water.
  • the process described above is characterized by a high cleaning effect. While about 99.9% of the solids or more than 95% of the inhibiting phenolic components are separated in the first two process steps, the biomass in the cleaned wastewater is completely removed.
  • the chemical oxygen demand can be reduced to less than 500 mg / L.
  • about 15 m 3 of biogas are provided for energy generation per cubic meter of wastewater to be treated.
  • the invention is not based on the embodiment described above limited. Within the scope of the invention, their Basic idea in biological wastewater treatment upstream separation of solids and oil as well an adsorption of phenolic components on an adsorber resin there are - also depending on the conditions in olive oil production and the resulting Wastewater - various modifications regarding the specific apparatus training in the individual process stages possible.
